I have (at long last) bought a new TV. In the setup, there is a choice between FRITZ!Box 7530 JE 2.4G or FRITZ!Box 7530 JE DFS. I see from a
Google search that DFS is Dynamic Frequency Selection and relates to
radar signals. Is DFS 5GHz only, so am I in effect being asked to
choose between 2.4 and 5 GHz? Is there a good way to know which to
choose or is it trial and error?

My approach is when in doubt, choose the one which is least likely to go wrong. The TV has to communicate with your router, and 2.4G is almost guaranteed to work.

I would try both. 5 GHz may give faster data speeds, though the
rate-limiting step will almost certainly be the WAN (internet) speed,
unless your TV needs to communicate with other computers/PVRs in the
house by network (as opposed to HDMI from PVR to TV). 2.4 GHz may work perfectly (up to the data speed that it negotiates) until other
unrelated devices running flat-out transfer lots of data over 2.4 GHz.
But if 5 GHz signal strength or quality (multi-path reflections) are borderline, you may get intermittent dropouts. See which works better
for you.

If you really can't use ethernet which is always the best then..
5GHz doesn't travel very far and is attenuated by walls, glass etc.
but that means less inference from neighbours. 5GHz is also likely to
be faster.
Install a free app on your phone which does wi-fi analysis and see
what the 5GHz signal is like at the TV. Maybe play with the aerials
on the router to improve this.
If good use that. If not use 2.4GHz.
Have a good look at ways you may be able to hide an ethernet cable.

Do your other devices offer such a choice? Or do they just offer a
single network called FRITZ!Box 7530 JE?
What model is the TV?

On a Fritzbox you could use one SSID for 2.4G and another SSID for 5G.

I did this at my previous place - two networks with different names. I
could then choose what I thought was more appropriate for each device.
Are there any implications for energy efficiency - would it double the
power at the router?

This is the only device to offer a choice.

Hmm, I wonder what would happen if your Fritz Box chose to use a 5GHz
channel that was not a DFS channel - would the TV start offering a
network called FRITZ!Box 7530 JE G5 instead?
Also, I wonder what would happen if you had a network with multiple
access points (a mesh for example). Would it offer the various APs >seperately?
I'd go with the "DFS" option to start with and change if it has
problems.
